  1. Sanitation and pest management Lecture 20

  2. The Truth About Pests • Pests are always present (ubiquitous) • Level of pest management determines the risk of infestation

  3. Perception vs. Reality • Is the facility really clean? • What is clean for you may be dirty for the pests!

  4. Important Pest Management Concepts • Keep pests below levels that do not result in economic losses • Apply pesticides only when needed • Use alternatives where feasible

  5. Suggested Pest Management Practices • Sanitation • Stock rotation • Inspection of in-coming ingredients • Monitoring • Selection and use of effective pest control agents • Evaluation

  6. Sanitation is the Single Most Important Pest Management Practice! • Raw grain • Grain handling equipment • Inside processing facility • Equipment • Floors/walls/I-beams/supports • Food contact surfaces • Electrical boxes

  7. Stored-product insects can develop on very little food!

  8. Energy Loss • Wheat - 1 kernel (34 mg) - 752 J • T. castaneum Dev 237 J • C. ferrugineus Dev 35 J • S. granarius Dev 345 J • S. oryzae Dev 130 J • R. dominica Dev 33 • E. cautella Dev 605 J

  9. Sanitation affects performance of traps. Traps covered with dust are less effective in capturing insects.

  10. Sanitation is important during heat treatment • …because heat does not penetrate grain or grain products!

  11. Sifter Temperature (oC) Roll stand Flour Bran Time (hours)

  12. Is Sanitation Enough?

  13. Retail store

  14. Sanitation should be followed by application of a pesticide!

  15. Food Increases Insect Survival • Cyfluthrin (205 WP, 9.5 g/94 m2) • No food – 100% knockeddown within 120 minutes, and none recovered Food – 100% knockeddown within 120 minutes, but 40% recovered after being placed on food

  16. Poor Sanitation Decreases Efficacy of Applied Insecticides

  17. Summary • Sanitation has many benefits • Sanitation has to be followed by fumigation of infested products or application of residual products (IGRs, inert dusts, Tempo) • Need seal all openings, cracks/crevices where dust accumulates • Evaluate effectiveness of sanitation by continuous monitoring and precision targeting of control measures
